my intel cpu, a P IV 3.0 GHz wih HT, used to run on 60 degrees with no
load, and 90 (sometimes 100~110) when playing 3d games. i tried adding 2
fans, but didn't help much, and then i found out i can decrease the temp
about 20 degrees by leaving the PC case open. now it's always open, it's
about 50 idle, and goes to a maximum of 80 when in a game.
the VGA used to also go up to about 120 when playing, nVidia cards
usually slow down upon reaching a certain temperature, and game
performance becomes choppy, signalling that it's time for a rest, but
now, with the case open, it only gets to more than 100 if i play for
more than 4 hours straight, which is becoming rare with all my uni load :P

i have never seen a processor getting damaged from temperature. once,
about a year ago, i removed my heatsink and replaced it improperly,
almost 20 seconds after starting the PC it went off. next time i tried
to start it, it gave me the thermal trip siren, and realized what was
going on, i eventually broke the heatsink screws, and had to replace it
with a new one. the only time i experienced an over heated processor.

on my old P III, 799 MHz, the thermal trip was about 50, and reaching 40
degrees was a **lot**, got me scared when i saw the average temp of
current processor.
